Abstract
A prism () is configured from a dielectric medium and is used in analysis using surface plasmons. The prism () is provided with an incidence surface () on which excitation light from outside is incident, a reflection surface () on which excitation light having entered the incidence surface () is reflected, an emission surface () from which excitation light reflected by the reflection surface () is emitted, and an opposing surface () opposing the reflection surface (). A gold film () is formed on the reflection surface (). The opposing surface () has a sink-mark surface (), and the sink-mark surface () is a transparent surface.
